This was what I call a big pack, spotted in the Pyrenees this summer (poor long range shot on the phone).
No it's not a hobbit!

I met a guy on the GR20 who had a pack like that; he was German....he carried all his food for the whole trip.
You really don't need to.
But he did.
"Some people never learn, his pack was big enough to carry a paraglider! Ah, ah!".
The main reason I share his hp with you is the fact,that he user a sub 1kg tent for his trips. @liamarchie (and many others incl.myself) doubted that it would be the right choice for this kind of trips but Bernie´s very happy with it.UL in a very different way.
